To all whom it may concem."

Be it known that l, JULIAN KENNEDY, a citizen of the United States, residing at Pittsburgh, in the county State of Pennsylvania, have invented a new and 'useful Improvement in lllanipulators for Rolling-Mills, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a plan View, partially conveiitional, of a rolling mill having my improved manipulator applied thereto;

Figs. 2 and 3 are sectional views taken on thc'lines ill-ll and, lllllll, respectively, of Fig. l, on a larger scale;

Fig. at is a detail. view showing in side elevation a portion of one of the guides;

Fig. 5 is a view partly in section and partly in elevation of a portion of the meclr;

anism for actuating the fingers; and

Figs. 6 and 7 are plan and elevations, spectively, of a portion of the actuating eonnections for the manipulator guides.

My invention has relation to manipulators for rolling mills, and is designed to provide a manipulator of simple, positive and ellicient character andwhich is applicable to various types of rolling mills.

A more particular object of my invention.

' is to provide novel means whereby the manipulator guides may be moved laterally oi the table and lengthwise of the rolls into any desired position and may be readily adjusted with respect to each other and with respect to the piece being rolled.

A further object of my invention to provide mechanism of improved character for operating the manipulator fingers.

The nature of my invention will he best understood by reference to the accompanydrawings, in which I have shown preierr'ed form-thereof and "which will now be described, it being premised, however, that various changes may he made in the details of construction and arrangement ol the various parts Without departing from the nd scope of my invention as defined appended claims.

la'r reference characters being applied to corresponding parts. The mechanisms for actuating the guides on the two tables are, however, connected so that both operations take place simultaneously on both tables.

Each pair of guides 6 and '1' is mounted for lateral movement on the transverse guide bars 8, being preferably rolleranounted, as indicated at J. Connected to the guides 6 ,by means of universal joints 10 are two actuating rods 11. Each of these rods is ,i'onnected at its opposite end to the hub porl loh 12 of a bell crank'lever 13, which is pivoted at 14 upon one arm of a triangular sup porting bracket 17. Also mounted on the center 16 is a two-armed lever 18, having one arm connected by a link 19 with one of the -arms or the bell crank lever 13. The other arm of each bell crank lever is connected by an actuating rod 20 at 10 with the guide 7.

21, 22, 23 and designate :four singleacting hydraulic motors. Themoto'rs 21- and 22 are located side by side at oneend portion of the mill, while the motors 23 and 24 are similarly located at the opposite end of the mill. The two motors 22 and 24 are connectedby a system of rods 25, which rods are also connected with those arms of the lovers 18 which are opposite the ends of said levers to which the links 19 are connected. The two motors 21 and 23 are connected in a similar manner by the rods 26 which are also connected at 27 to the triangular levers l5.

lly admitting pou to the cylinder 21 an to the cylinder :23, the triangular levers l5 areall rocked on the centers 16 in one carried on and moving has a-concavity 44 therein to fit a portion of I I 16, and through the connections 19 and bell cranks 13 move the rods 20 to. adjust the guide 7 with respect to guide 6; .or e ther cylinderj22 or 23 may be operated independently of cylinders 21 and 23, at any time, to adjust the guides 7 laterally with I respect to' guides 6;

Each of the guides 6 has a plurality of "projections 28, in which is journaled a mafixed on arock shaft 32.

nipulator shaft 28 Rigidly secured to this shaft is a crank arm 29, which hasthe u'niversal joint connection .30 (see Fig. 2) with a hub portion of a lever arm 31 which is This rock shaft is connectedto a lug 33 on the guide 6, and is mounted to slide endwise in bearings 34 of a stand 35 as said guide is moved carrying .With it the collar 31. 3.6 is a'double-acting hydraulic cylinder, whose plunger 37 is connected by links 38, with a crank arm 39 on said shaft 32. The manipulatorshaft 28 has a plurality of crank arms 40, to each of I through the connections described, the mampulator shaft 28. As this shaft is rocked,

which is pivoted at 41 a manipulator finger 42. Each of these fingers has an extenslon 43, back of its pivot 41, and such extension tween the guides 6 and 7. Power being admitted to the cylinder 36, the plunger 37 is actuated to rock the shaft 32, and thereby,

the crank arms are moved from the p0sitions shown in dotted lines to the positions shown in full lines in Fig. 2, thereby carrying the manipulator fingers forwardly through the openings in the guide 6; and by reason of the engagement of the heel portionsof these fingers with the shaft 28, the fingers are caused to move upwardly as they are movedforwardly, thereby catching and turning the work piece, The plunger 37 is then reversed and the fingers moved back to the position shown in dotted lines-in Fig. 2.

This movement ofthe manipulator fingers is an exceedingly simple and positive one,

by reason of the provision of the fulcrum of their heel. portions against the shaft 28, giving them a powerful lifting and turning action.

It will be obvious that many changes may be made in the details of construction and arrangement of the parts, without departing from the spirit and scope of the invention as defined in the appended claims. Thus, lnstead of hydraulic cylinders for operating the various parts, I may use any other suitable kind of motor; the details of the actuating connections between the motors and the movable parts may be varied, and numerous other changes may be made, limitedonly by the scope of the claims.

; The particular description and arrange- .ment of the manipulator herein shown and described forms the subject matter of my divisional application Serial No. 142,784, filed January 17, 1917.

l. A manipulator for rolling mills, comprising a pair of'laterally movable guides, connections for simultaneously movmg both guides, and other connections for moving one of the guides relatively to the other, together with motive means for actuating said connections, substantially as described.

'2. A manipulator for rolling mills, comprising a pair of laterally movable guides,

separate actuating connections for each guide, motive means for simultaneously actuating the connections of both gu des,

and other motive means for separately actuating the connections of one of the guides, substantially as described.

3. In a'manipulator-for rolling mills, the combination with a pair of separately movable lateral guides, of lever members having actuating connections with both guides,

and motive means whereby the actuating connections of both of the guides may be simultaneously moved and whereby the actuating connections of one of the guides may be independently moved, substantially as described.

4. In a manipulator for rolling mills, the combination with a pair of guides mounted for lateral movement, separate actuating connections for each guide, a lever member,

a bell crank mounted on said lever member,

and to which the actuating connections of both guides are attached, motive means connected to the first named lever member, a second lever member connected to the said bell crank, and other motive means connected to the second lever member, substantially as described.

5. A manipulator for rolling mills, comprising a pair of laterally movable guides, separate actuating connections for each guide, a plurality of lever mechanisms for simultaneously actuating the connections of both guides and for separately actuating the connections of one of the. guides, connections between the several lever mechanisms, and motive means for actuating the last named connections, substantially as described.

In testimony whereof, I have hereunto set my,hand.
